Embodiment Construction

[0008] Take 14.5% of the original drug chlorpyrifos, 0.5% of the original drug emamectin benzoate, 8% of the emulsifier (0203B), 10% of the solvent (DMF), and 67% of the solvent dimethylbenzene. Drop into reactor and stir, treat to be dissolved in 60 minutes and evenly rear sampling detection analysis it reaches technical indicator of the present invention (dusapi% (m / m) ≥ 14.5, emamectin benzoate % (m / m) ) ≥ 0.5, moisture % (m / m) ≤ 0.5, acidity (in H 2 SO 4 Calculated)% (m / m)≤0.5, the stability of the emulsion is qualified, the stability of cold storage and hot storage is qualified), and then pumped into the settling tank, high-level tank, and treated by the filter, it becomes a product that can be packaged.

[0009] The invention has a good control effect on paddy rice leaf curl. Attached is the field efficacy experiment report of "Chlorpyrifos Emamectin Benzoate EC".

Abstract

The invention relates to chlorpyrifos.dimethylamino avermectin benzoate missible oil which is built with raw medicine chlorpyrifos, raw medicine dimethylamino avermectin benzoate, emulsifier (0203B), solvent (DMF) and solvent xylene. Field medicinal effect test shows that the medicine is used to prevent rice leaf roller pests, has small application amount, high pest destruction speed, long effect period, no pesticide harm, prevention effect up to about 93 percent, and is good for reducing the rice production cost and increasing the profit of farmers.

Description

technical field [0001] The invention relates to a pesticide for preventing and controlling rice pests, in particular to a pesticide for preventing and controlling rice leaf rollers, namely a kind of chlorpyrifos emamectin benzoate EC. Background technique [0002] my country's rice production has long been trapped by the frequent occurrence and spread of rice leaf roller pests. In order to eliminate this harm, farmers widely and repeatedly apply relevant pesticides supplied on the market. The pest of rice leaf roller not only failed to curb, but also enhanced the resistance to pesticides, so farmers had to increase the amount of pesticide application and increase the frequency of pesticide application, but the result was very little effect. Production costs are rising, environmental pollution, and human and animal safety are threatened. People are eager to supply efficient, low toxicity, quick-acting pesticides for the control of rice leaf rollers on the market. Contents...
